Specification of Letters Patent.

Patented May 14, 1907.

Application filed February 5.1907. Serial No. 365,862.

To all whomit may concern:

Be it known that I, AMEDEE FAYOL, a citizen of the Republic of France,residing at Bordeaux, 9 Rue Matignon, in the Republic of France,engineer, have invented certain new and useful Improvements in Boats, ofwhich the following is a specification.

My invention relates to improvements in propeller ships and has for itsobject to construct a device of this character so as to be provided withlongitudinal keels and to carry, between the said keels, one ormorescrew propellers, actuated by a motor or engine mounted on a frame abovethe water. The floating of the apparatus is insured by means of eitheran aerostat or of freely revolving floating cylinders, or both thesemeans at one and the same time.

One embodiment of my invention is shown in the accompanying drawings, inwhich:

' Figure 1 is a longitudinal sectional view of the propeller ship; Fig.2 is a transversal sectional vilgw of the same; and Fig. 3 is a plan Themain frame of the apparatus is comosed of two secondary lateral verticalfiames 1 braced at the top by cross pieces 2, and carrying at theirlower portion longitudinal keels 3 designed to insure the rectilinearmovement of the propeller. Two of the cross pieces 2 also carry a as acage or well 5 in w screw propeller 6. The latter, axial line of theapparatus, keels, is actuated by means of located in the between the amotor or en 4, and through the medium of sprocket or other suitablegearing 8.

At the front and rear of the ship are located floating cylinders 9revolving freely around their axes 10 carried by the lateral frames 1.On the platform 4 loosely rest two casings 11 designed to receive thepassengers, the goods, and the like, and forming a double supportingbody for such passengers and goods. The said casings are preferablyassembled the one with the other by rigid cross-pieces 12.

To steer the ship, use is made of the rudthe keels 3 and which can beactuated from the platform 4, on which the steerer stands, through themedium of sprocket, cord, pull, or other suitable gearing. The motor orengine being in operation, the screw propeller is revolved, and

latform 4, as well iieh is mounted a I produceskthehpropulsion of theapparatus. The efliciency of the screw propeller is as high as itpossibly can be because the apparatus offers no obstacle at all to themotion of the water either at the front or rear of the screw propeller.On the other hand, the cylinders 9 revolve in moving forward and, asthey are absolutely loose on their axes, they take a tangential speedequal to the speed of the propeller itself. The resistance o posed bythe said cylinders is of very sma l extent as they are absolutely smoothand havenoagitating effect on the water; the saidresistance is all thesmaller as through the effect of the speed the cylinders are raised upand glide so to say on the surface of the water. Such being theconditions, the result is that the ship can easily reach very highspeeds. The peculiar mounting of the casings 11, on the platform 4 allowof their becoming immediately detached from the ship in case the lattershould, by reason of the bursting of one of the floating casings or thelike, sink in the water, so that the passengers would remain abovewater.

The number of the floating cylinders, the number of the screwpropellers, the position of the latter, as well as the minor details-ofthe construction of the apparatus, may be varied without departing fromor sacrificing any of the advantages of this invention.

Any number of keels may be used and screw propellers may be locatedeither in all the intervals between the keels or in certain intervalsonly. If only a single keel is used, screw propellers will be locatedsymmetrically at both sides of the said keel. Of course, the motor ofthe screw propellers may be actuated by any motive power, even by humanpower, and instead of a single motor for actuating one or several screwpropellers, there may be arranged as many motors as screw propellers ora different number.

Claims.

1. A ship comprising the combination of a frame having parallel keels offloats mounted in the said frame both in front and at the rear, a screwpropeller carried by the frame between. the keels and at a lower levelthan that of the floats, a platform on. the frame, a motor or enginesecured on the said platform, and a supporting body for passengers andgoods loosely located on the platform.

2. A ship comprising a frame having parallel keels, floats mounted inthe said frame I a platform on the frame, a cage or Well suspendedunderneath the said platform, a screw propeller mounted in the cage orWell, a-motor or engine in the middle of the platform adapted to actuatethe screw propeller,

and a supporting body for passengers and goods comprising two casingsloosely located on the platform alongside the motor or enlo gine, andcross-pieces or braces connecting the said casings other.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of tWo subscribing Witnesses AMEDEE FAYOL.
